Embodiments for Carrying Out the Invention

[0011] Hereinafter, a case for a video display device according to an embodiment will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the following embodiments, and can be appropriately modified and implemented within the scope of not changing the gist thereof. In the following figures, for convenience of explanation, some configurations may be omitted. Also, in the following description, unless otherwise specified, "up", "down", "left", "right", "front", and "rear" are used based on the directions indicated by the arrows in each figure (with the user as the reference). However, the orientation of each configuration in the following embodiments is merely an example, and can be changed to any orientation.

[0012] [First Embodiment] Figure 1 is a schematic perspective view of the video display device and the case for the video display device according to the first embodiment. Figure 2 is a schematic perspective view of the case and the video display device according to the first embodiment. As shown in Figures 1 and 2, the video display device 50 is housed in the case for the video display device (hereinafter simply referred to as "the case") 10. In other words, the video display device with a case 1 is configured to include the case 10 and the video display device 50. First, the schematic configuration of the video display device 50 will be described below.

[0013] The image display device 50 is a device known as VR goggles and is used in close proximity to the user's eyes. The image display device 50 is a device that allows users to virtually experience images such as video footage as if they were projected onto a large screen. The image display device 50 comprises a main unit 51 and a battery unit 52 which is separate from the main unit 51. The main unit 51 and the battery unit 52 are connected by a strip-shaped cable 53 for power supply. The cable 53 is folded and bundled and housed in the case 10.

[0014] The main unit 51 has a housing 55 that is rectangular in shape, elongated horizontally when viewed from the front, with each corner being arc-shaped. The housing 55 extends generally in the front-to-back direction, but is formed in a tapered shape that widens from front to rear. A cable 53 is connected to the top surface 55a of the housing 55.

[0015] Figure 3 is a bottom view of the case and video display device according to the first embodiment. As shown in Figure 3, the bottom surface 55b of the housing 55 is provided with an operating area 56 where buttons such as a power button and a USB port are arranged on the left and right sides.

[0016] The housing 55 is formed with an open rear end 55c. As shown in Figure 2, the rear end 55c of the housing 55 is formed with a recess in the center that is further forward than the left and right sides, according to the shape of the user's face. Furthermore, the lower central part of the rear end 55c of the housing 55 is formed with an even greater recess according to the user's nose.

[0017] Figure 4 is a rear view of a video display device with a case according to the first embodiment. Figure 5 is a rear view similar to Figure 4, with some components of the video display device disassembled. As shown in Figures 4 and 5, a partition wall 58 is provided on the rear end 55c side of the housing 55, extending in the vertical and horizontal directions. The partition wall 58 is located on the rear end 55c side of the housing 55.

[0018] A pair of lenses 60 are provided side by side on the left and right of the partition wall 58. The partition wall 58 has a pair of openings for holding the lenses 60, and the edges of these openings are made thicker to form a holding portion 58a into which the outer circumference of the lenses 60 can be fitted (see Figure 6), and the lenses 60 are held via the holding portion 58a. Since the rear end 55c side of the housing 55 is open, the partition wall 58 and each lens 60 can be exposed at the rear of the housing 55 (towards the front in Figures 4 and 5). The lower central part of the partition wall 58 has a recessed portion 58b formed to accommodate the user's nose. The recessed portion 58b is provided at a position corresponding to the recessed portion in the lower central part of the rear end 55c of the housing 55.

[0019] Each lens 60 is positioned facing the user's eye when the image display device 50 is in use. In this embodiment, various types of convex lenses such as biconvex and plano-convex lenses can be used as lenses 60, and they can also be used as part or all of the optical system to achieve a desired focal length and optical characteristics.

[0020] Figure 6 is a schematic cross-sectional diagram illustrating the first embodiment of a case-equipped video display device. Note that in Figure 6, the battery unit 52 and cable 53, as well as some of the internal components of the housing 55, are not shown. As shown in Figure 6, a video display device 62 is provided in front of the lens 60 inside the housing 55. The video display device 62 can be a liquid crystal display panel in which pixel circuits are arranged in a matrix in the display area corresponding to pixels. Furthermore, the video display device 62 can be configured in various ways as long as it can project an image onto the user's eye through the lens 60, and an organic EL panel or the like may be used instead of a liquid crystal display panel. In addition, the video display device 62 may be used by detachably installing an external terminal device such as a smartphone inside the housing 55.

[0021] The image display device 50 includes a plate 64 positioned at a predetermined distance behind the lens 60, a shielding portion 65 for the lens 60, and a contact member 67 provided on the rear end 55c side of the housing 55. The shielding portion 65 is formed by being laminated on the rear surface of the plate 64. Therefore, the shielding portion 65 is integrated with the plate 64, and this integrated configuration can be used as an attachment 68. This makes it possible to add the attachment 68 to the image display device 50 to obtain the functions of the shielding portion 65 described later. In addition, the attachment 68 can be easily attached to and detached from the image display device 50, and maintenance and replacement of the attachment 68 can be easily performed.

[0022] The plate 64 is positioned inside the housing 55 from the rear end 55c side of the housing 55, and the front surface of the plate 64 (attachment 68) abuts against the holding portion 58a of the partition wall 58. The plate 64 is made of a transparent (highly transparent) material that transmits light in the thickness direction. The plate 64 can be made of organic glass or inorganic glass as the light-transmitting material, but from the viewpoint of strength and cost, it is preferable to make it out of acrylic resin or polycarbonate.

[0023] The contact member 67 comprises a cushion member 67a that contacts the user's face and a connecting portion 67b that is connected to the front end of the cushion member 67a and fitted to the rear end 55c of the housing 55. The connecting portion 67b of the contact member 67 contacts the rear surface of the attachment 68 when fitted to the rear end 55c of the housing 55. As a result, the attachment 68 is sandwiched from the front and rear by the connecting portion 67b of the contact member 67 and the holding portion 58a of the partition wall 58, and the attachment 68 including the plate 64 can be held via the contact member 67. Note that the contact member 67 can be configured in ways other than fitting by the connecting portion 67b, as long as it can be mounted at the rear of the housing 55. For example, as shown in Figure 4, hook fasteners 69 (shown by dashed lines) may be provided on each of the surfaces where the cushion member 67a faces the upper wall 12, left wall 14, and right wall 15 of the case 10 (described later), and the contact member 67 may be detachably attached to the rear of the housing 55 by these hook fasteners 69. In this case, hook fasteners 70 (shown by dashed lines) may be provided on each of the surfaces where the attachment 68 faces the partition wall 58, and the attachment 68 may be detachably attached to the partition wall 58 by these hook fasteners 70.

[0024] Returning to Figure 5, in the attachment 68 including the plate 64, a recessed portion 68a is formed at a position along the recessed portion 58b of the partition wall 58. Also, in the contact member 67, a recessed portion 67c is formed at a position along the recessed portion 58b of the partition wall 58 and the recessed portion 68a of the attachment 68. Therefore, the recessed portion 68a of the attachment 68 (plate 64) and the recessed portion 67c of the contact member 67 are formed in the area corresponding to the user's nose, similar to the recessed portion 58b of the partition wall 58. With the formation of the recessed portion 68a of the attachment 68, the recessed portion 67c of the contact member 67 passes through the recessed portion 68a and is received by the recessed portion 58b of the partition wall 58.

[0025] The shielding portion 65 is a sheet-like or film-like member laminated on the rear side of the plate 64. The shielding portion 65 is configured to perform both of the following first and second functions. The first function is to allow the image inside the image display device 50 that has passed through the lens 60 to be projected onto the user's eyes. The second function is to block or attenuate sunlight that enters the lens 60 from outside the image display device 50. The first and second functions of the shielding portion 65 will be described below.

[0026] When a user views an image on the image display device 50, which is in a state where the first function is performed, the user's eyes are close to the lens 60, and the rear end 55c side of the housing 55 is largely closed. In this state, a dark state is ensured both inside and outside the housing 55 on either side of the lens 60, and the image from the image display device 62, which is the image inside the image display device 50, is displayed. The light of the displayed image passes through the lens 60 and then enters the shielding part 65. The shielding part 65 transmits all or most of the light of the image that has passed through the lens 60. As a result, the shielding part 65 allows the light of the image to be projected onto the user's eyes, and thus performs the first function. In other words, in the usage state of the image display device 50, the shielding part 65 is configured to have a low reflectivity to the light of the image that has passed through the lens 60 and entered from the front, allowing the user to see the image.

[0027] An example of a situation in which the second function is performed is when sunlight shines into the housing 50 of the video display device 50 with the rear end 55c side facing upward. In this state, the shielding part 65 reflects all or most of the sunlight that enters the shielding part 65 from the opposite side (rear side) of the lens 60. As a result, the shielding part 65 performs its second function by blocking or attenuating the sunlight that enters the lens 60, and consequently blocking or attenuating the sunlight that enters the video display device 50.

[0028] When sunlight entering the lens 60 is attenuated by the shielding portion 65, the heat rays contained in the sunlight are also attenuated, and even if the sunlight entering the lens 60 is focused inside the housing 55, it is possible to avoid high temperatures in the housing 55 and the focused area of ​​the video display device 62. Also, when sunlight entering the lens 60 is blocked by the shielding portion 65, sunlight does not enter the lens 60, and the lens 60 cannot focus light, so it is possible to avoid high temperatures in the housing 55 and the video display device 62.

[0029] Furthermore, the shielding portion 65 may be configured to absorb sunlight in addition to or instead of reflecting or attenuating sunlight as described above. This absorption function reduces the amount of heat rays contained in sunlight transmitted through the shielding portion 65. Therefore, even if sunlight incident on the lens 60 is focused within the housing 55, it is possible to avoid high temperatures in the housing 55 or in the focused area of ​​the video display device 62, thereby enabling the second function to be performed.

[0030] The attachment 68, in which the shielding portion 65 is laminated and integrated with the plate 64, has a structure known as a one-way mirror, half mirror, or magic mirror.

[0031] The shielding portion 65 can be exemplified by a configuration in which at least one of a light-reflecting layer that reflects incident sunlight and a heat-absorbing layer that absorbs incident sunlight is provided on the surface of a transparent film-like substrate. An adhesive layer for laminating the shielding portion 65 onto the plate 64 is provided on the back surface of the transparent film-like substrate.

[0032] The light-reflecting layer of the shielding portion 65 has the function of reflecting all sunlight. Alternatively, it may have the function of reflecting some or most of the sunlight and transmitting the remaining sunlight, that is, it may be configured to attenuate sunlight and reduce the occurrence of light concentration on the image display device 62 via the lens 60. A specific example of the light-reflecting layer is preferably a metal vapor-deposited layer, but other metal sputtering layers, metal plasma layers, metal powder compounding layers, metal plating layers, chemical plating layers, etc., may also be used. The type of metal used is preferably aluminum, but other examples include gold, silver, copper, nickel, cobalt, chromium, tin, indium, etc. The light-reflecting layer may be configured by laminating a film to perform the same function as the metal vapor-deposited layer as described above.

[0033] The heat-absorbing layer of the shielding section 65 is a layer capable of absorbing infrared rays, and is, for example, a layer containing an infrared absorbent. The heat-absorbing layer of the shielding section 65 is capable of absorbing at least the infrared region of sunlight incident on the lens 60. Specifically, examples include a film layer in which an infrared absorbent is kneaded into a transparent substrate film, a coating layer containing an infrared absorbent, and a printed layer containing an infrared absorbent. As infrared absorbents, inorganic infrared absorbents such as tin oxide, indium oxide, indium tin oxide, magnesium oxide, titanium oxide, chromium oxide, zirconium oxide, nickel oxide, aluminum oxide, zinc oxide, iron oxide, antimony oxide, antimony-doped tin oxide, lead oxide, and bismuth oxide, and organic infrared absorbents such as phthalocyanines, naphthalocyanines, and anthraquinones can be used.

[0034] The transparent film-like substrate of the shielding portion 65 can preferably be a polyester resin film, and other examples include films of various resins such as polyvinyl chloride resin film and polyolefin resin film, or laminated films thereof.

[0035] Next, Case 10 will be described with reference to Figures 1 to 3, as well as Figures 7 to 13. Figure 7 is a front view of the case according to the first embodiment. Figure 8 is a rear view of the case according to the first embodiment. Figure 9 is a top view of the case according to the first embodiment. Figure 10 is a bottom view of the video display device with case according to the first embodiment. Figure 11 is a side view of the case according to the first embodiment. Figure 12 is a cross-sectional view taken along line AA of Figure 7. Figure 13 is a diagram showing an example of the usage state of the video display device with case according to the first embodiment.

[0036] As shown in Figures 1 and 2, the case 10 includes a case body 11 that houses both the battery unit 52 of the video display device 50, with the battery unit 52 at the front and the main unit 51 at the rear. The case body 11 is made of a suitable synthetic resin. The case body 11 includes an upper wall 12, a lower wall 13, a left side wall 14, and a right side wall 15 that extend in the front-to-back direction, and a front wall 17 that is provided slightly behind the front ends of these walls. The case body 11 may also be made of paper, wood, aluminum, or other metals with a low specific gravity.

[0037] The case body 11 has an upper wall 12, a lower wall 13, a left side wall 14, and a right side wall 15 that are formed as cylindrical bodies so that they can be positioned along the housing 55 of the video display device 50 to be housed. These cylindrical bodies extend generally in the front-to-back direction, but are formed in a tapered shape that widens from front to rear according to the shape of the housing 55. The rear end (one end) of the case body 11 is not closed and an opening 19 is formed. With the video display device 50 housed in the case body 11, the lens 60 of the video display device 50 is positioned on the side of the opening 19 (see Figures 5 and 6).

[0038] The front end (and other end) of the case body 11 is closed by a front wall 17. The front wall 17 is formed in a curved shape, with the center bulging forward from both ends in the left-right direction. Here, the aforementioned battery unit 52 has a curved shape, and the front wall 17 is formed in a curved shape that follows the curved shape of the battery unit 52. This reduces the empty space of the case body 11 and improves stability by reducing the space that moves when the housing 55 and battery unit 52 are housed inside the case body 11.

[0039] Extension pieces 17a are formed in a series on both the left and right ends of the front wall 17 (the right side is not shown in Figures 1 and 2). The extension pieces 17a are bent to follow the inner surfaces of the left wall 14 and the right wall 15 and are attached to the left wall 14 and the right wall 15 via grommets 25, which will be described later. The front wall 17 is also joined to the inner surfaces of the upper wall 12 and the lower wall 13 via L-shaped piece members 21.

[0040] An elongated rectangular hole 12a is formed in the upper wall 12 of the case body 11. The cable 53, which is folded inside the case body 11, is fitted into the rectangular hole 12a.

[0041] As shown in Figure 3, the case body 11 has a slot-shaped window portion 13a extending horizontally in the lower wall 13. The window portion 13a is formed according to the operating area 56 on the lower surface 55b of the housing 55 of the video display device 50, allowing access to the operating area 56 through the window portion 13a (see Figure 10). A reinforcing wall 22 is provided in the central part of the lower wall 13 in the horizontal direction, extending in the front-to-back direction. The reinforcing wall 22 is divided into two parts so as not to overlap with the window portion 13a.

[0042] As shown in Figures 9 and 10, the rear ends of the upper wall 12 and lower wall 13 of the case body 11 are formed with the central part recessed forward from both the left and right sides, according to the shape of the user's face. Therefore, the case body 11 is formed so that the rear regions of the left wall 14 and right wall 15 protrude rearward, and these rear regions serve as light-shielding walls 23. In other words, at the rear end (one end) of the case body 11, light-shielding walls 23 are formed on both the left and right sides in the direction of alignment of the pair of lenses 60 (see Figure 5), and the light-shielding walls 23 block light from entering the case body 11 from the outside. Furthermore, the central part of the rear end of the lower wall 13 is formed with a further recess according to the user's nose.

[0043] Holes 24 are formed on the front end (other end) of the left wall 14 and right wall 15 of the case body 11. More specifically, the holes 24 are formed either immediately before the front end of the left wall 14 and right wall 15, or with a small gap between them and the front end. Each hole 24 is formed by providing a grommet 25 in a hole (not shown) directly formed on the front end of the left wall 14 and right wall 15. These holes 24 and grommets 25 constitute a connection portion 26, and the case body 11 has connection portions 26 at two locations, left and right. Each connection portion 26 is located at the vertical center of the left wall 14 and right wall 15. The grommet 25 penetrates the extension piece 17a of the front wall 17. Therefore, the extension piece 17a has the function of fixing both the left and right sides of the front wall 17 and the function of reinforcing the grommet 25.

[0044] As shown in Figure 13, a long strap S is connected to the connecting part 26. Connecting fittings Sa are provided at both ends of the strap S, and these connecting fittings Sa are kept inserted through the holes 24 of the connecting part 26. The connecting fittings Sa are not particularly limited, but can be made up of snap hooks, D-rings, carabiners, or combinations thereof.

[0045] When a user carries or transports the case-attached video display device 1, the strap S is passed over the shoulder or neck and held by the user. At this time, the case-attached video display device 1, including the case 10, is suspended by the strap S. In this state, the connection part 26 side, which was the front of the case 10, is positioned vertically upward, and the opening 19 side faces downward.

[0046] According to this first embodiment, when a user views an image on the image display device 50, they hold the case 10 containing the image display device 50 with both hands and bring the contact member 67 on the opening 19 side into contact with their face. This brings the lens 60 close to the user's eye, and the image displayed on the image display device 62 is projected onto the user's eye through the lens 60.

[0047] When the opening 19 side of case 10 is brought close to the user's face, the inside of case 10 becomes dark, and the entire image display device 50 is also placed in a dark space. In this state, the shielding part 65 located between the lens 60 and the user's eye allows the light of the image that has passed through the lens 60 to pass through, so that the user can view the image on the image display device 50. The image display device 50 is equipped with a detection unit such as a proximity sensor (not shown) that detects whether the user's face is close to the detection unit, and controls the ON / OFF of the image display device 62 according to the detection result.

[0048] Furthermore, since light-shielding walls 23 are formed on both the left and right sides of the case body 11, it is possible to block light from the outside of the case body 11 into the inside and maintain a good dark state inside the case 10.

[0049] Furthermore, when a user temporarily stops viewing images on the image display device 50, they are likely to adopt a posture where they move the contact member 67 away from their face and hold the case 10 with both hands. In such a posture, the opening 19 side of the case 10 and the rear end 55c side of the housing 55 of the image display device 50 may face upward. In such cases, if the image display device 1 with the case is used outdoors, sunlight will enter the shielding part 65 inside the housing 55. As described above, the shielding part 65 has at least one function of blocking, attenuating, or absorbing sunlight, so it can prevent sunlight from entering the lens 60, or even if sunlight enters the lens 60 and is focused inside the housing 55, it can suppress the area where the light is focused from becoming hot. This makes it possible to avoid damage inside the housing 55 and the image display device 62 caused by light focusing by the lens 60.

[0050] Furthermore, a connecting portion 26 is provided so that the strap S can be easily attached to the opposite side of the opening 19 of the case body 11. By attaching the strap S, when the user carries the case-attached video display device 1 without viewing the video on the video display device 50, the strap S can be passed over the user's shoulder or neck to hold the case-attached video display device 1. Holding it in this way causes the case-attached video display device 1 to be suspended by the strap S.

[0051] In this configuration, as shown in Figure 13, the connection portion 26 side, which was previously the front of the case 10, is positioned vertically upward, and the opening 19 side can be positioned downward. In other words, the rear end 55c of the housing 55 and the lens 60 of the video display device 50 housed in the case 10 can be positioned downward. When used outdoors, sunlight shines from above or diagonally upward, so it is possible to prevent sunlight from entering the downward-facing lens 60. Therefore, even when the user is not using the video display device 50, it is possible to prevent sunlight from entering the lens 60, and damage to the video display device 62, etc., caused by light concentration by the lens 60 can be avoided.

[0052] In this way, by providing the connecting part 26 on the case body 11, it is possible to suspend and hold the case with the strap S, and in turn, to carry the case with the lens 60 facing downwards, thereby preventing damage from sunlight.

[0053] Furthermore, since the connection part 26 is provided on the front end side opposite to the opening 19 of the case body 11, it becomes easier to maintain the lens 60 facing downwards when the case 10 is suspended by the strap S. Moreover, since the connection part 26 is provided in two places, on the left and right, it is possible to attach both ends of the strap S in the longitudinal direction and make it easier to suspend and hold the case.

[0054] Furthermore, since the connecting portion 26 has a hole 24, it can be easily connected to the connecting fitting Sa, increasing its versatility for various long objects such as straps S.

[0055] [Second Embodiment] Next, a second embodiment of the present invention will be described with reference to Figures 14 to 25. In the following description, the same reference numerals may be used for components that are the same as or equivalent to those in the first embodiment, and their descriptions may be omitted or simplified. Figure 14 is a schematic perspective view of the case-equipped video display device according to the second embodiment. Figure 15 is a schematic perspective view of the case and video display device according to the second embodiment. Figure 16 is a front view of the case according to the second embodiment.

Figure 19 is a bottom view of the case according to the second embodiment. Figure 20 is a side view of the case according to the second embodiment. Figure 21 is a side view of the case with the cover member open, similar to Figure 20. Figure 22 is a cross-sectional view taken along line BB in Figure 16. Figure 23 is a rear view of the case-equipped video display device according to the second embodiment. Figure 24 is a rear view of the case-equipped video display device with the cover member open, similar to Figure 23. Figure 25 shows an example of the usage state of the video display device with a case according to the second embodiment.

[0056] As shown in Figures 14 to 17, in the second embodiment, compared to the first embodiment, a pad 31 is provided on the rear end side of the case body 11, and a cover member 32 (not shown in Figures 14 to 16) is provided to open and close the opening 19 of the case body 11.

[0057] In the second embodiment, the pad 31 is made of a cushioning material such as foamed resin. The pad 31 is attached to the rear ends of the upper wall 12 and lower wall 13 of the case body 11. There is one pad 31 attached to the upper wall 12, and both ends of it are provided to extend so that they are located near the left and right ends of the upper wall 12. There are two pads 31 attached to the lower wall 13 (not shown in Figures 14 and 15), one on each side, so as to sandwich the area corresponding to the user's nose.

[0058] In the second embodiment, the case body 11 is provided with a pad 31, thereby omitting the contact member 67 in the video display device 50 of the first embodiment. The attachment 68 of the video display device 50 (see Figure 24) can be configured to be held in the same position as in the first embodiment by providing, for example, an appropriate fitting structure on the inner surface of the housing 55. Alternatively, the attachment 68 may be attached to the partition wall 58 or the holding part 58a, or it may be attached detachably by providing hook-and-loop fasteners on the opposing surfaces of the partition wall 58 or the holding part 58a.

[0059] The cover member 32 is made of a suitable synthetic resin, similar to the case body 11. As shown in Figures 17 to 24, the cover member 32 is formed by bending a single plate-like body. The cover member 32 comprises a fixed surface portion 34 formed in a rectangular shape and fixed to the inner surface of the left side wall 14, and a cover body 36 connected to the fixed surface portion 34 via a bent portion 35 and formed to a size that fits inside the case body 11. The bent portion 35 is formed by a groove or the like extending at the boundary between the fixed surface portion 34 and the cover body 36. A semicircular notch 36a is formed on the upper end side of the cover body 36.

[0060] The cover body 36 is provided so as to be displaceable in a direction that allows it to rotate with the bent portion 35 as the center of rotation, and this displacement allows it to open and close the opening 19 of the case body 11. Specifically, in the state shown in Figure 23, the cover body 36 is positioned along the vertical and horizontal directions and fits inside the case body 11, closing off most of the opening 19 except for the four corners. In this state, the rear of the lens 60 (towards the front in Figure 23) is covered by the cover body 36.

[0061] Furthermore, the cover body 36 can be rotated backward from the state shown in Figure 23, so that it is positioned along the front-to-back direction as shown in Figures 21 and 24. In this state, the cover body 36 is retracted from the opening 19 of the case body 11, opening the opening 19, and the cover body 36 no longer covers the rear of the lens 60. Then, the shielding part 65 (attachment 68) is exposed behind the image display device 50. In this way, the cover member 32 can switch between a state in which the rear of the lens 60 is covered and a state in which it is retracted from the rear of the lens 60 by opening and closing the cover body 36.

[0062] With the cover body 36 closing the opening 19 of the case body 11, a block-shaped stopper 38 is provided at the rear adjacent position on the right end of Figure 23, which is the tip side of the cover body 36. The stopper 38 restricts the cover body 36 from rotating in the direction of opening in the state shown in Figure 23. Therefore, as shown in Figure 25, even if the case body 11 is suspended with the opening 19 facing downwards, the cover body 36 can maintain a closed state without opening the opening 19.

[0063] To release the cover body 36 from a state where it is blocking the opening 19 of the case body 11, the user applies an intentional external force with their fingertips or the like to pull the cover body 36 backward. This causes the cover body 36 to elastically bend and deform, and the tip of the cover body 36 moves backward while rubbing against the stopper 38, enabling the opening operation.

[0064] Furthermore, when the cover body 36 closes the opening 19 of the case body 11 from an open state, the user simply needs to point the opening 19 of the case body 11 upwards. This causes the front end of the cover body 36 to rotate in the direction of falling due to its own weight, that is, in the direction of closing the opening 19. This rotation in the closing direction is accelerated by the cover body 36's own weight. Therefore, just before the cover body 36 closes the opening 19, the front end of the cover body 36 comes into contact with the stopper 38, but as the cover body 36 elastically bends and deforms, the front end of the cover body 36 rubs against the stopper 38, and the rotation in the closing direction continues. Due to this continued rotation of the cover body 36, the front end of the cover body 36 is positioned in front of the stopper 38, and the cover body 36 closes the opening 19, and this state is maintained by the stopper 38.

[0065] Thus, according to the second embodiment, by simply turning the opening 19 of the case body 11 upward, the opening 19 can be closed by the cover body 36 without touching or operating the cover body 36. As a result, the lens 60 can be effectively covered by the cover body 36 in the upward position of the opening 19, which is prone to sunlight entering the lens 60, thereby better preventing sunlight from entering the lens 60.

[0066] Furthermore, as shown in Figure 25, even if the opening 19 of the case body 11 is facing downwards, the stopper 38 can maintain the state in which the opening 19 is closed by the cover body 36, thus preventing the cover body 36 from unintentionally opening and becoming loose.

[0067] Furthermore, the present invention is not limited to the embodiments described above, and can be implemented with various modifications. In the embodiments described above, the size, shape, direction, etc., shown in the accompanying drawings are not limited thereto, and can be appropriately modified within the scope that allows the present invention to exert its effects. In addition, the present invention can be implemented with appropriate modifications as long as it does not deviate from the scope of its objectives.

[0068] For example, the shielding portion 65 can be modified in various ways, such as its shape and position, as long as it performs the functions described above. For instance, the shielding portion 65 provided on the rear surface of the plate 64 may be provided on the front surface or both sides of the plate 64, or the attachment 68 may be omitted and the shielding portion 65 may be formed on the surface of the lens 60 by laminating it with a coating or the like.

[0069] Furthermore, in the first embodiment, the attachment 68 including the shielding portion 65 was held between the contact member 67 and the partition wall 58, but the attachment 68 may also be attached to the contact member 67 by fitting or the like. In this case, the contact member 67 may be attached to the opening 19 side of the case body 11 instead of being fitted to the rear end 55c side of the housing 55.

[0070] Furthermore, the connecting portion 26 may be modified insofar as it allows for the connection of a long object such as a strap S. For example, the connecting portion 26 may be a hole formed in the case body 11 itself, or a ring member or the like may be provided on the case body 11 to allow for the connection of a long object.

[0071] Furthermore, while we have described the case where strap S is used as the long component, the length and shape of the long component are not limited to that of a strip, string, or chain-shaped component.

[0072] Furthermore, the video display device 50 may omit the separate battery unit 52 by incorporating the battery into the main unit 51.

[0073] Furthermore, the shape of the housing 55 of the video display device 50 may be other than those of the embodiments described above, and is not limited as long as it can be accommodated in the case 10.

[0074] Furthermore, the rectangular holes 12a and window portions 13a of the case body 11 may be formed in different positions or omitted depending on the configuration of the video display device 50. [Industrial applicability]

[0075] This invention relates to a case for a video display device that can prevent damage to the inside of the video display device caused by sunlight. [Explanation of symbols]
